Abstract
The invention discloses a printed circuit board (PCB) protection structure for an alternating current/direct current electromagnet. The PCB protection structure comprises a PCB, wherein electronic components are welded on the PCB; a protection shell of which the shape is matched with the PCB and the shapes of the electronic components on the PCB is arranged on the PCB; the protection shell accommodates the PCB and covers one surface and all side surfaces of the PCB; the sides, corresponding to the PCB, of the protection shell extend out each side surface of the PCB; a layer of low-temperature glue is injected into another side surface of the PCB to form a low-temperature glue layer; and the low-temperature glue layer is connected with the protection shell to form an integrated structure which covers the PCB and the electronic components on the PCB. By the PCB protection structure for the alternating current/direct current electromagnet, (1) the electronic components are safer and cannot be rushed disorderly or rushed away; (2) the reliability of a product is enhanced and the performance of the product is improved; and (3) the cost is saved indirectly and the profit space is improved.
Description
Technical field
The present invention relates to a kind of pcb board protection structure of alterating and direct current magnet.
Background technology
At present, the electronic component that alternating current-direct current transforms electromagnet adopts the form of soldering to be welded on the pcb board, causes the direct exposure of electronic component on pcb board, and tinol will melt about 180 degree simultaneously.And the temperature on the pcb board can reach about 250 degree in follow-up injection moulding process, therefore is easy to make the weld of electronic component and pcb board to melt when injection moulding, causes electronic component to be dashed, thereby influences the stability of product.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of pcb board protection structure of alterating and direct current magnet, can effectively protect pcb board and on the safety of electronic component, avoid electronic component to be dashed, thereby guarantee product quality stability.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of pcb board protection structure of alterating and direct current magnet; comprise pcb board; be welded with electronic component on this pcb board; other be provided with a shape and described pcb board and on the containment vessel of electronic component profile coupling; this containment vessel is ccontaining in it and cover surface and all sides of described pcb board with described pcb board; and each side that the side of each side of the corresponding described pcb board of this containment vessel stretches out described pcb board; in addition inject one deck low temperature glue in the another side of described pcb board and form a low temperature glue-line, this low temperature glue-line and described containment vessel be connected to form one structure with described pcb board and on electronic component coat in it.
As a further improvement on the present invention, connect by soldering between described electronic component and the pcb board.
As a further improvement on the present invention, described electronic component is at least one of diode and PIN pin.
The invention has the beneficial effects as follows: 1. electronics is safer zero point, does not have by towards unrest or dash phenomenon.2. strengthen reliability of products, promoted the performance of product.3. indirect saving cost, promoted profit margin.
Description of drawings
Fig. 1 is low temperature glue-line of the present invention and described containment vessel decomposition texture schematic diagram.
By reference to the accompanying drawings, make the following instructions:
1---pcb board 2---electronic component
3---containment vessel 4---low temperature glue-line
Embodiment
By reference to the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, namely the simple equivalent of being done with the present patent application claim and description in every case changes and modifies, and all still belongs within the patent covering scope of the present invention.
As shown in Figure 1; a kind of pcb board protection structure of alterating and direct current magnet; comprise pcb board 1; be welded with electronic component 2 on this pcb board; other be provided with a shape and described pcb board and on the containment vessel 3 of electronic component profile coupling; this containment vessel is ccontaining in it and cover surface and all sides of described pcb board with described pcb board; and each side that the side of each side of the corresponding described pcb board of this containment vessel stretches out described pcb board; in addition inject one deck low temperature glue in the another side of described pcb board and form a low temperature glue-line 4, this low temperature glue-line and described containment vessel be connected to form one structure with described pcb board and on electronic component coat in it.Like this, in follow-up process of injection molding because pcb board and on electronic component coated in it fully, even forming temperature is high again, can not influence being connected of electronic component and pcb board yet, thereby guarantee the stability of product quality.
Preferably, connect by soldering between described electronic component and the pcb board.
Preferably, described electronic component is at least one of diode and PIN pin.
